- RubyGems now uses persistent connections on index updates. Index updates are much faster now.
- RubyGems only updates from a latest index by default, cutting candidate gems for updates to roughly 1/4 (at present). Index updates are even faster still.
- gem list -r may only show the latest version of a gem, add --all to see all gems.
- gem spec now extracts specifications from .gem files.
- gem query --installed to aid automation of checking for gems.
gem update --system (you might need to be admin/root)NOTE: if you're on an old RubyGems (before 0.8.5), Eric recommends this:
gem install rubygems-update (again, might need to be admin/root)or simply fall back to download the RubyGems 1.1.0 release from RubyForge, unpack the archive, go to the created directory and do:
update_rubygems (... here too)
ruby setup.rb (you may need admin/root privilege)
Lincoln Stoll helped me shake the last bugs out of RubyGems, so we integrated it into Rubinius. We decided to make it a subcommand rbx gem like rbx compile or rbx describe. There are still a few things broken in RubyGems, namely installing gems with extensions because mkmf.rb doesn’t work in Rubinius.
Lincoln also pointed out and gave me patches for a few backwards-compatibility problems with RDoc, so now both RubyGems and RDoc work on Rubinius.
